Creating Numeric Buckets

The other day I was writing some code that was needed for a report. Part of the report was to take a number (integer) and fit it into a set of "buckets" at intervals of 100, rounded up. Confused? Here's some examples of what I needed:
3 --> 100
101 --> 200
1536 --> 1600
64 --> 100


Here's the line of code I used to accomplish it:
newNumber = ( ceil( myNumber/100 ) ) * 100;

Certainly not the most cerebral code ever written, but (hopefully) worth sharing.

This type of problem (creating numeric buckets) is fairly common and I was wondering if anyone else had a different way of solving it?
